Kanzaki-Carl Hurth KBW20

[briblack]

another perfect day in paradise . . . .

We're in Taiohae, Nuku Hiva, and our tranny has started to make bad noises. I would like to get a new one, or used but working ok, or a rebuildable core that I can have rebuilt. And $hipped in.

Any leads out there? I've checked e-bay. It's on the back of a Yanmar 4JHT2-TE.

Thanks

A KBW 21 would also work. Any out there?

The KBW20 is not that hard to take apart and rebuild. The main four bearings should be (from my rebuild log, please double check dimensions):
Input shaft: 2x SKF or similar 32007
Output shaft: 2x SKF or similar HR30208J


In my case, I had a screeching noise from the tranny. It was a bad bearing on the input shaft, the closest one to the engine. I did a crappy rebuild job to get me going (only changed the bad bearing, but cleaned & flushed the others), and once home, changed all the bearings, including the many needle rollers.



The service manual for the 4JH2-TE can be found online and includes directions for the transmission. You may need a shim-set to get that axial shaft play right. A machine shop may cut them from shim stock. You also need bearing pullers and a 'special' tool to get the nut out of the shaft coupling.



If you don't feel comfortable, with the service manual, and the parts, any machine shop should be able to to the job.
